Study of Immune PID Adaptive Controller and Its Applications in Thermal Control System

Abstract

Due to the characteristics of large inertia, long time lag and variation with time for the thermal control system in power plant, conventional PID control strategy can't achieve satisfied control effect. Biology immune system is characterized by its strong robustness and self-adaptability even when encountering amounts of disturbances and uncertain conditions. Prompted by the regulation rule of biology immune feedback response, an immune PID adaptive control strategy for thermal control system is presented in this paper. Simulation results show that this control strategy is superior to conventional PID control. It can adapt the changing of object's parameters and has strong robustness, self-adaptability and disturbance rejection ability. Keywords: Immune system; Immune feedback; Immune PID adaptive control; Thermal control system
